We're Growing Twice as Much Food (with Far Fewer Farms) Than We Used To
How do you grow more
USDA put together
this curious little chart of what we've been putting into our farms since 1948, versus what we've been getting out of them. Most immediately striking is the huge rise in how much food we're getting out of farms today. But look a little closer and you may notice something odd. The strange thing about this data is not the fact that
farm production almost doubled

Why is it so weird? Because we actually have
much less farmland today
The last six decades or so have been huge in terms of figuring out how to use basic farm technologies - ranging from the big machinery that overtook farms (making most farm laborers obsolete), to the more modern incarnation of plants hybridized in the lab to suit specific needs. Figuring out how to do that was a big enough investment that it almost completely balanced out the dip we would have seen from the loss of all those farm workers and
In a lot of ways, the message is comforting: If we could figure out ways to grow less with more before using technology, then can't we simply keep doing it? In some ways we can, although changing climates are tightening resources (water, topsoil) in ways that were never a problem before. A lot of the jump that we see in the chart was from farm technology like automatic sprinklers, for instance.
Certainly, there are still ways out there to keep upping the amount of food we grow, but it's just as likely that we can expect that the increases of the future will be much more modest-and come at a higher price.
